Comparative evaluation of salivary cortisol levels in bruxism patients before and after using soft occlusal splint: An in vivo study

Objective: The purpose of this in vivo study was to compare and evaluate the clinical efficacy of two gingival retraction systems; Ultrapak and Traxodent, on the basis of the amount of gingival retraction achieved in vertical and horizontal direction and their hemorrhage control. Methods: A total of 60 subjects were selected requiring fixed prosthesis. The two gingival retraction systems were used on the prepared abutments randomly. The vertical gingival retraction was measured before and after retraction using flexible measuring strip with 0.5 mm grading. The horizontal retraction was measured on the casts poured in polysilicone impressions made before the retraction and after retraction. Results: Statistically significant difference (p<0.05) was found between the amount of the retraction (vertical and horizontal) achieved by Ultrapak as compared to Traxodent. However, in achieving hemostasis Traxodent showed better efficiency than Ultrapak (p<0.05). Conclusion: The mean retraction width and depth achieved with retraction cord (Ultrapak) was significantly greater when compared with retraction paste. Although retraction paste (Traxodent) showed bleeding index significantly less when compared to that of retraction cord (Ultrapak).

Cortisol Levels

Although mental disorders are common among university students, the majority of students with mental health issues do not seek out treatment during their academic life. The aim of this study was to evaluate the effects of a novel group approach- choir singing, and its potential impact on stress, via salivary cortisol levels and self-reported stress levels in university students during 4 sessions of choir singing. It was based on a quasi-experimental research conducted with 25 Brazilian university students. Each choir singing session lasted 60 minutes. A question was asked before and after the intervention: what is the level of your stress? Salivary cortisol was collected before and after the intervention. After the choir singing intervention, there was a statistically significant reduction in self-reported stress (p<0.0001) and salivary cortisol levels (p<0.0001). This research suggests that choir singing can reduce the self-reported stress of university students after 4 weeks of follow-up with ∆= 45.83% and salivary cortisol levels in the first week with ∆= 3.57%.
